MACHINE 'FOR sTRETcHIN'G onori-iin THE PROCESS or FULLING.

To all whom t may concern.'

Be it Aknown that we, BAXTER D. lVHir NEY and GEORGE W, LAwTomof Winchendon, Worcester county, Massachusetts, have` invented and applied touse certain new and useful improvements of machinery for Apreparing and `stretching cloths both widtl'iwise and lengthwise Vduring the proeess'of fu'lling Athe same and `also after they are fulled o'rf steamed in order to .produce a lsmooth sur- 2) by 'means ozf'ain intervening toothed pinface thereon.

The said improvements, the vrinciples thereof, and manner in which we ave-con-- templated their application, together with such parts, improvements, or combinations"L we claim as our invention and hold to lbe original and new, we 'have herein set forth and described, which description taken in connection with the accompanying drawings Iherein referred yto composes our specification.

well as lengthwise by hand Vpower. This stretching `prevents warping or v-curling (as termed :by the workmen) of the the cylinders.

A, A, A, in all the different drawings is the framework, which lmay ybe constructed of, iron, wood, or any other suitable material*y and may be arranged in any proper manner, to answer its extended purpose of support-y ing and connecting the operating parts of length, the teeth pointing or being bent as the machinery.

A cross shaft B C (Figs. 1 and 2, Plate 1,1

and Fig. :1,-Plate 2) revolving in suitable 'boxes or bearings, a, a, placed on the sides During the process of fulling cloths it often necessary lto remove them yfrom the` fulling mill, and stretch them widthwise asf the 'driving power, andI which iinpartsa ro tary Vni'ption to said shaft, runson Athese pulleys. A right threaded screw l) E (Fig. 1, Plate 2) is'cut or otherwise properly formed on'one half of the shaft or from 'D l:to 'E ywhile a lift threaded screw E F is also Aformed on the other half'or from E to F.

A small pinion G (Fig. jl, Plates 1 and 2) onthe endC'of the shaft B, C, engages with a veogged wheel -I (see Fig. 1, .Plates land a lever L, `M, N 'is inserted. The fi'ilciu'mfof the lever "is A small dog 4or `pin (Fig. 1, Platef2) project'sffroni the i'iiside'of the cogged wheel 'I, which pin when the wheel I is moved-inward, by -forceapplied "to the extremity L ofthe lever L M N, vcomes in contact with a similar p'in or l`dog'g 'projecting VYfrom "the side of 'the shaft d e and thus connects said cogged wheel I with the shaft d 'e 'causing them to revolve together. :Another cogged `wheel O (Figs. "1 and 2, Plates 1 and'2) is 'pla/ced on'one endoffa small 'horizontal shaft h 1l (Fig. v1, Plate 2, Fig. 2, Plate 1), the journals of'said vshaft, revolving in suitable bo'Xes or beariiigspat 7c and Z. By means ofthe `lever L M N, and whenevernecessary) the cogged wheels C) and I can be made to engage with each other. A Vchuck P is 'placed'on one end of `the shaft la, z'. This chuck has a squarefor other `proper shaped Ychamber into which the vend Q of a cylinder or roller Q R is inserted seen in thesection '(Fig. 2, Plate 1). Anv The cogged wheel 'I being moved out of On shifting `the driving belt upon the fast pulley the cylinder o-r barrel K issetfi'n motion in a direction indicated by the arrow m (Fig. 2, Plate l), thus winding the cloth around the periphery of said cylinder. The

, belt is then to be. thrown on the loose pulley i should be passed' upward over the threads of v the screws on the shaft R, C, to the strip T 0 and the opposite end ofthe piece of cloth U of card wires on the roller Q R, pressing the edge of the cloth on the same to secure its adhesion. Y

A spring, r, s, e and Fig. l, Plate 2) vis attachedat its footto the side of the frame. It has a small pin c (Fig. l, Plate 2) projecting frolnits side, which pin,.on raising the lever 0. 29 (which lever when down rests against the .Shelf 71,

on theside of the spring) falls onto a notch Y or hole inthe side of the chuck P, as the `c ard wires T U are brought into a suitable position to attach the extremity of thepieceof cloth to them. When the lever 0l p is raised.

. chuck the lever o p will drop uponthe'friction drum Y; This operationv being completed, the lever L MN is then to be shifted ,so as to cause the cogged wheels I and O, to

l 'gear with eachother, and the driving belt changed to the surface of the fast' pulley.

The barrel or roller QR is thus put in ino-V tion in the direction indicated by t-he arrow fa (Plate 1, Fig. v2) and draws' the clothV away from the surface of the cylinder K, at

one end of thebarrel K, a narrowfriction drum or pulley Y (Plate 2, Fig. `1) is'iXed on the-shaftcl, e. A lever o p whose fulcrum isat one extremity 79, rests on the pe#v riphery of the drum. Aweight, Z, is hung on or attached to the opposite end of thel'e ver. Thefriction thusV created on the drum .Yfretards the revolution Vof the `barrelwor cylinder K andstret'ches thevpcloth length` wise. Itwill be perceived that fasthe cloth presses over the screw D E,`E F, the thread f of saidscrew acting in opposite directions,

each other but not so Vvfar as to engage the .cogged wheel Iwiththe shaft d e. `The cloth `is then to bey removed, by drawing it from the roller Q R, whichwith theshaftz' can be freely revolved during the operation.

Instead of the rightand left rthreaded and as the 4lugs or segments are at the same time moved sidewiseor laterally, the cloth is thus stretched widthwise. Y

VThe segments Gr H I K of which 'there maybe any suficient number, Y havev 'each a dovetailed ledge or strip oflmetalg hf?) 7c, Fig.` 3, at-` tached to their under sides: The sections of these ledges are exhibited more particularly in Fig. 3, Plate 2. The'circularjplates or ,heads A B rC D have dovetailed or 'proper shaped spaces Z, mnt, 0, Fig. 3, formed or the segments has a small roller p attached p to the lower side ofthe ledge as represented in Fig. 2,` by.. dotted lines. These rollers traverse'in a windingor spiral groove ls t u shown by dottedlines `formed in a cylinder Ader L,` as tocause each of theledges .as it traversethrough the upperhalf of its circle of revolutionto recede'or move outwardin alongitudinal direction, and' also while they are traversingl through the lower halfof `the circle of their revolutiongto'return to their former position.` These ledges are iluted or groovedtransversely as seen in the drawings served that when the cloth isdrawn tightly over the segments,fby the action of the drawingV roller Q` R` the' nap or under 'surface must sink into'the grooves g, g, g', g, so that as the segmentsmove laterally, in' apa'rallel direction to thev centerr shaft, thecloth `must be stretched widthwise. f e The saving of` handlabor by the substitutionof ourmachinery is very great. The

machinery maybe applied] :for stretching the cloths; after they are fulled and steamed, in order to produce a smooth surface on them. We thus `add.firmness to the \teXture, land `cause them to hold out ,in length, betterthan they would otherwise, do.A p
